Corvus Glaive is the merciless servant of the Mad Titan Thanos. The most loyal of the lieutenants in the Black Order, Corvus Glaive is the most favored by Thanos, having cruely betrayed his own people to achieve glory with Thanos. He is husband to fellow Black Order member Proxima Midnight.
Corvius Glaive alongside Supergiant were sent to the Jean Grey School for Higher Learning as part of Thanos' invasion.
Corvus and Proxima faced the Avengers (including Captain America, Captain Marvel, the Hulk and Hyperion) once they finally located Thanos. Proxima and Corvus easily handled the Hulk when he arrived ahead of the others. The two proved to be more than a match for the team. Captain America deflected some of Proxima's deadly attacks, some of them hitting Corvus. This gave Hyperion the chance to destroy him.
Proxima quickly gathered his blade, saying "I have it. I have you." This may indicate that Corvus can be resurrected through his weapon. Proxima (holding Corvus' blade) and Thanos were incased in a form of 'living death' by Thane.
The cube of living death was taken by the Illuminati for safe keeping. But while they struggled to stop the destruction of Earth when the Universal Incursions began, they failed to notice Corvus reforming around his weapon.
After the destruction of their first alternate Earth, the Illuminati disbanded. Namor released Thanos, Corvus and Proxima from their prison, as well as prisoners Terrax and Black Swan to form a new Cabal. Together they would destroy the alternate Earths with great pleasure.
